Place all the chocolate in a large crockpot.
Cook on low for approx 30-60 minutes (time will vary depending on crockpot), or until all chocolate is melted. Stir frequently to ensure it doesn't burn around the edges and bottom.
Turn off crockpot, add peanuts, and stir until thoroughly mixed.
Take a teaspoon and drop large spoonfuls of the mixture onto wax paper.
Drizzle with caramel topping. I filled a sandwich bag with about three tablespoons of caramel, cut a small hole in the tip of the bag, and then drizzled.
Once everything has cooled, store in an airtight container.
Yield varies depending on size of clusters. I made fairly large clusters and had about 48 pieces with one set of ingredients.
